There are two pages (let's say page1 and page2).
The first page contains numerous photos. Each photo contains a checkbox. If that checkbox is checked, a div opens revealing multiple select menus for choosing a number of photo prints at each size. It would looks something like this when the div opened:
4"x6" [select a quanitity]
5"x7" [select a quanitity]
8"x10" [select a quanitity]
So the user checks of all the photos that they want, and then select a quantity of each size for those specific photos. The user then presses a submit button, which leads us to page2.
Page2 is used to process this info. All of the info from the photo form is then echoed for the user to review. So it might look something like this:
Review your order:
Photo 1 - (2) - 4"x6" prints, (4) - 5"x7" prints
Photo 2 - (3) - 4"x6" prints, (1) - 8"x10" print
All of that works fine. The photo selections are echoed perfectly.
Page2 also contains a simple form to take in name, email, etc. The form also contains a hidden input field to pass along the order. At this point, if the page is refreshed, or if the user attempts to send the form, but gets errors in form validation, all of the values disappear. That is because the variables were being set based on the POST values from the previous page. So, of course, if the page is refreshed for any reason, the POST values no longer exist. So I started using SESSIONS to set all of the values so that they would still show up, even on refresh. Everything is working fine now, although you told me I was using SESSIONS improperly. I'm not quite sure how I'm using them improperly, though.
